stuff you're doing while at home
yesterday terri and me levelled the 2 other 'bays' to be concreted by lunchtime which gave us all afternoon to concrete the outer 2. by almost the end of the first it was clear we weren't going to have enough ballast for all 3 so i decided to substitute a couple of shovels of the remaining bag of sub base to each mix to 'a' use that up and 'b' get more done. the stones are bigger of course but as long as the depth of concrete is more than the size of the biggest stones it's not an issue. once proven at the end of that first bay we continued with the mix in all of the second until we were done. now we could work out how much more ballast and cement was needed for the middle bay which is slightly wider than the other 2 by about 10". the reason for the bigger middle bay is simple, when i was shuttering them i used my 6' spirit level working off of the 'footings' each side. this left a bigger bay in the middle which doesn't matter as long as the tamping board is long enough. i've ordered the ballast and cement which won't be here until next tuesday so we'll get the last bit done wednesday, at least my back will have a chance to rest up :rolleyes:
